    97 Mercedes E420 Plugs, Wires, Coil Packs Rplcmt

    Dada5 Congrats on your new car. While 320k miles is a lot, the wires on these cars are usually replaced in singles as needed. Check the resistance of each wire- if one is in spec, keep using it, if out of spec, replace only that one wire(this is not chevy). If you replace all 16 wires, it will...

    What if jack stands fail?

    You would need a wheel inside the tire to offer last ditch protection. If I have to work under a car supported by jack-stands, I prefer to keep the floor jack in slight support of the vehicle and an additional jack stand or a complete wheel as a "just-in-case." Dr. Olds

    AMSOIL AND A 2014 CHEVY SILVERADO

    If you continue to use E85 and get an oil analysis done, it won't be very promising OAI, even though the factory fill stuff likely a good oil from the start. E85 tends to break down the oil TBN at an accelerated rate no matter what brand you use. E85 also comes with a fuel economy penalty. I had...

    2010 VW TDI w/DPF Delete - alternative to 507

    Slipstream, It sounds as if you know your topics. Since you have removed the DPF, you can potentially run any decent diesel oil. Hopefully, you will see greater longevity for the major components (turbo; inj. pump; engine, etc.). I don't know if your engine had problems specifically due to the...

    best stop leak additive

    Stop leak will not help the described problem. Head gaskets normally should have ZERO sealant of any kind applied. They keys to a successful head gasket installation are: clean block and head surfaces; "NEW" head-bolts and an accurate torque wrench. My questions are 1. did the machine shop...

    thick10w30or0w40 for summer 98 corolla

    I can't believe I have to point out that the flush is to be run for 10 minutes per the directions at IDLE! I'll be more specific in the future. If you misread my post and thought that I meant to drive the car with the flush in, I obviously meant "(at oil change)" add flush for 10 min. & run at...

    thick10w30or0w40 for summer 98 corolla

    First, lets solve your problem. Problem: neglected engine w/ sludge build up in the oil system. 1. If you can pull both valve cover and oil-pan and clean them, much sludge will be gone. 2. New PCV valve which is likely clogged due to lack of maintenance. 3. Run a few short OCIs w/ whatever...

    New(To Me) '90 740 With Bad Fuel Economy + Tick

    When did this car last have its "flame trap" serviced?" (PCV system). The flame trap is often neglected on Volvos. A plugged PCV system can cause problems. All the other suggestions were good. Are there any DTC fault codes. If yes, address them. If not, then the flame trap is a possibility if...

    GL-4 or GL-5?

    Rand got it right, GL-5 if for differentials. GL-4 is for manual transmissions with yellow-metal synchros. I would go with synthetic GL-5 in both differentials. The way you can determine if you have a limited slip differential is to: 1. Either find the tag that identifies the exact...

    Another 68 Plymouth question

    All the fluids need to be flushed, especially coolant and brake fluid. For oil, go with a quality 10W-40 or 15W-40 w/ engine oil flush before draining and using a few short OCIs. For the transmission, it should use ATF+4 which is an improved version of ATF+2 and ATF+3. The +4 additive pack is...

    AMSOIL and leaks

    I think the grey RTV is what should be used. There are also special grey RTV sealers specifically for differentials. I have done a number of Ford differentials in recent years and several were filled with Amsoil differential oil. In no cases did I have any leaks. I doubt that any specific brand...

    40AMP + Charger/Power Supply

    I agree with eljefino, 40amps is ridiculous. What is the source of this recommendation? 40 amps is more appropriate for boosting a discharged battery to start the car. 6amps should do for programming.

    What Is A 73 Buick Electra 225 Worth 89,000 Miles

    I see you have gotten lots of advice. The real question is what do you want to do with this car once you acquire it? It is a '73 smogger w/ EGR and points distributor combined that really kills the fuel economy. Try to get it as cheaply as possible. Below $2000 is an appropriate price. This car...

    Premature Oil Breakdown

    If you smell fuel in the oil, you have fuel system problem. Get this checked by a pro who knows your make & model of bike. excessive fuel getting into the oil can cause expensive problems if not addressed promptly. I doubt the brand of oil is relevant in this case. No brand of proper oil that...

    HD Motorhome usage of Valvoline Dexron VI ATF

    I would go with either Amsoil Torque drive or Castrol Transynd fluid. The Dexron VI is too thin for this application.

    Oil Change & Gear shifting jerkiness

    What I suspect is more of an electronic- machanical problem. Your 2013 5.7 Hemi has VVT(variable valve timing) and MDS (multiple displacement system). Either of these is sensitive to oil viscosity. Dexos 1 spec is not likely relevant. You should be able to use any brand of 5W-20 you choose if it...
